To ALL WHoMlfr MAY' ooNCEnN: A

- Be. .it known that I, WILIAISLI HARVEY, of Volga City, in the countyofClayton, invented certain new anduseful Improvements inSulky-Cultivators;

is a. suHiciently-full, clcar,ande`xact description thereof,` to-enahle'ene skilledjin the art to which my said inventin .appertains tomake and Acar and State'of AIowa,A have form a. part of-this,specification.

Thesubject o f my invention' isa sulky or wheel-cultivator,

to be so-held as-to fhroiiy the'idirt either vtoward or away from t Myimprovements consist-'- l First, inthe novel 'combination andarrangement oflthe devices for supporting, dodging, and raising theshovels; and A' l 'i i' I Second, in a simple device for holding tlieinner. shovels at'di'eien purpose of throwingv the dirt either tovard oraway from the plants.

' A In the dra'vvingsv i Y Figure 1 is a. plan vieivof my improvedcnltivator, aportion of the'fram'e-being broken a.\vay to morefulilyillustrate-the'arrangement of some of its parts. I I

I Figure 2 isa longitudinal section on the line :zzafflig. 1.

Figure- 3 is a perspective view of'a'modicationof my cultivatorfaportion of thefiaine andr one of the he plants,.as desired.-

supporting-'wheels beingmemoved to exp'ose'the patsibehind them.

.Figure 4 isa diagramlrepresenting in detail the manner-of adjusting'theinner shovels.

Similar letters of reference indicate corresponding partein-thefseve-ral figures. may represent the frame, Whichmay be-of anyeditable form to afford attachment for the dilerent parts; 'Bistheaxle-tree, C the tongue,- D the wheels, and E the drivers seat. i. FFerney represent the front-or inner shovels, andF F the rear or outsideones. The formexjF, are` con nect'ed'to the frame by means Aof thestaples f and a, so as to allowthem'to he turned in any desireddirection,

. de'vcesvbeing employed to impart sa d motonsto them, and hold them inthe desired positions, as vill behereinaiter described; t `braces G. v

I I are chains, connecting theloiver ends of the shovels` F and F vtoper'foratdstraps J J', which. are supported by being passed` throughslots inr the frame, as shoivn in iig. Land having a wooden lpin,7',inserted' in -on'e of their perforations above said frame, thevertiealadjustmeni; of said pin the perfor-ations of said' straps helatter ones F are ivoted to th4 frame, and 'su orteda ainsi; lateralmovement by f p e Pp g regulating the workingdepth of the shovels.

K is a roek-bar, pivoted in,lu gs a at the front of the frame, and'having depending', fromits lover side, arms- ]c k", .to the lower endso'i` v which are secured, by ho-oke, (as shown, or o`therwise,') chainsL L', connecting them respectively to the shovelsF and Ft I M is alever,'projlecting rearward from the rock-bar K, at nbout right anglesto its depending arms. Itfis,

-if necessary, bent at m, to -allow itsmovement toentend-'above'the'axle-tree, andis `provid-ed at its loose extrem- -itywitlla treadle', in', within convenientreaclrof the drivers foot. Bydepressingthis trea`d1e, the's'hovels are smxiltaneously raised ari-dsuspended, for ridingover obstructions, or'goin'g to and from thefield.,

v'N N, are a; pair of'bent levers, pivoted atthe outer edge of ,the`frame A, in brabkets af', their' lower arms 'beingrconnected by barsorchains O to` the inner shovels F, for the purpose of dodging them, toavoid plants,

ahdvtheixi'upper members'formi'ng' treadlcsnfwhioh,being depressed-bythefoot of the' driver, impartt'his I The upper endsof vthe'inn'ershovels,are 'provideflon their front andre'ar lsides with 'staples ff', forthe-reception 4of hooksP P', of diilerent lengt-li, by the lchnnge'fofwhich, as illustrated in iig. 4, the shovels are and I'dohereby declarethat the following y it into eect, reference beinghad to theaccompanying drawings, which` l in which the s ho'vels are capable-of,being dndge'd,l and in which the innershovels-'are adapted' `t anglesrelatively to the roiv, for the turned, so as to throw the dirt towardoraway from the row, the black linesA in said ligure representing theposition of the'hooks and shovel-standards when arranged 'to i throw thedirt toward, and the red lines their positions when throwing it awayfrom the row.

In fig. 3, the rock-bai' K is shown as, being hinged to the lower sidesof the frame, and its motion imparted to it by a lever, cf, connected toan arm, 7cm, of said rock-bar, by a rod, k. The shovel-standa-idsiF andF" are supported'by being swivellcd and pivotecl respectively to pivotedbars z'*z'*l, the swinging movement of which is limited by slides orclutches '5*2, and the' elevating-chains L L supplaced by bars Z* 2*. f

Having thus described my'invention, the following is what I claim asnew, and desire to secure by Letters I Patent:

1f The combined arrangement of the shovels F F', supporting-chains I,I', perforated straps J J', and.

wooden pins j, the rock-bar K k c, elevating-chains L L', and treadle Mm', and the dodging-chains O, and treadles N, all as represented anddescribed, for the purpose set-forth. A

2. -The hooks P P,'e mployed, in combination with the inner shovels.F F,to adjust said shovels relatively to the row, substantially as and for.the purpose specified. i

To the above specification of myzinvention, I'have signed `my hand, this14th day of March, 1868.
